Hi,
There were few cases where SSSD seems to stop working and required restart
when the server's load average gets high ~ 80 on 24threads(processors)
platform.
Running 6.5 centos with 1.9.2-129 x86_64
On 6.5,
sssd_nss.log shows the following:
Thu Jul 31 20:28:38 2014) [sssd[nss]] [sss_dp_init] (0x0010): Failed to

Also the /var/log/messages:

Seems like restart @20:30:25 didnt properly restart sssd daemon? I believe
1.9.2-129 is the latest avail?
enumerate is false, ldap_network_timeout is 5 and we have multiple ldap_uri
settings where hosts are separated by ","
Would appreciate if you can shed some light on this. Thanks.
